The Washington Redskins spent the second day of free agency hosting a handful of prospects and lining up visits for another. They also made one depth signing.

The team added offensive tackle Bruce Campbell — a former Maryland Terrapin who was a fourth-round pick of the Oakland Raiders in 2010 — to a one-year deal.

Meanwhile, the team hosted longtime Houston Texans defensive end Antonio Smith and former Baltimore Ravens cornerback Corey Graham , who opted to sign with the Buffalo Bills.

Former Pittsburgh Steeler and Redskins safety Ryan Clark was scheduled to arrive in Ashburn on Wednesday evening, and his visit was expected to last into Thursday.

Clark, who turns 35 this fall, spent the first two seasons of his 12-year career with the New York Giants, then played for Washington in 2004 and 2005. The Redskins allowed him to depart via free agency in 2006, and he spent the past eight seasons with the Steelers, helping them win Super Bowl XLIII in the 2008 season and earning Pro Bowl honors in 2011.

The free safety made 104 tackles and two interceptions last season.

Washington needs help at safety after the contracts of Brandon Meriweather and Reed Doughty expired this offseason. The Redskins declined to engage in bidding wars for Jairus Byrd, T.J. Ward or Mike Mitchell — the top safeties on the market.

Smith did not immediately sign with Washington, and it remains unclear where things stand with him.

Campbell, meanwhile, has a chance to compete for playing time with second-year backup tackle Tom Compton and possibly push right tackle Tyler Polumbus for snaps. He remains relatively inexperienced, however.

The 6-foot-6, 320-pound Campbell spent the first two seasons of his career with the Raiders and the 2012 season with Carolina. The Panthers waived Campbell with an injury last August. Campbell has appeared in 19 games, starting none.

The Redskins maintained their cautious overall approach to free agency while figuring out how to spend the remainder of their cap room.

They entered Tuesday’s signing period with $18.58 million in cap space, according to figures released by the NFL, and committed $9.83 million of that money to five players. That left the Redskins with $8.75 million in cap space before their one-year, $710,000 deal with Campbell.

Inside linebacker Perry Riley Jr.’s new three-year deal with the team is worth $12 million and includes $5 million of guaranteed money. His cap hit for 2014 is $3 million.

Wide receiver Andre Roberts’s four-year, $16 million contract came with a $4 million signing bonus and $8 million guaranteed. His cap hit for 2014 is $2.25 million.

Guard Shawn Lauvao’s four-year contract is worth $17 million, with $5 million guaranteed. His cap hit for this season is $3 million.

Linebacker Adam Hayward signed his deal Wednesday morning. The three-year, $3 million deal came with a $300,000 signing bonus and $500,000 guaranteed. His cap hit for 2014 is $955,000.

Wide receiver Santana Moss signed a one-year deal for the veteran’s minimum of $955,000. He received a signing bonus of $65,000. His cap hit for this year is $620,000.
